Please combine to consult Fig. 1 and Fig. 3, this fixture 10 comprises base plate 11 and is convexly set in the some baffle plates 13 on base plate 11 circumference at interval.In preferred embodiment of the present invention, described baffle plate 13 axial fourth class cyclotomy are provided with.The inboard base plate 11 of this fixture 10 is provided with one or four electromagnet 15, and each electromagnet 15 is connected with corresponding baffle plate 13.The free-ended section of said electromagnet 15 is provided with retainer 17, and this retainer 17 is made up of some gear teeth.

This keeper 20 roughly is an annulus, spaced apart four storage tanks 21 that are provided with on its excircle, and each storage tank 21 is used for an end of ccontaining baffle plate 13.

This housing 30 comprises an a junction 31 and an extension 33, and after this housing 30 was installed on fixture 10, these keeper 20 restriction connecting portions 31 are extreme position in axial sliding, prevents that housing 30 breaks away from from fixture 10.This extension 33 is provided with two installation portions 35.In preferred embodiment of the present invention, said two installation portions 35 are oppositely arranged.Offer a through hole 351 on each installation portion 35.Be set with a magnet 37 on the relative side of this connecting portion 31 and extension 33, convex with auxiliary section 39 on this connecting portion 31, this auxiliary section 39 roughly is a gear-like, and this auxiliary section 39 is used for being meshed with retainer 17.

In preferred embodiment of the present invention, this first power take-off mechanism 60 comprises an internal gear 61, forms conical gear on the inboard of one of which end.

Each second power take-off mechanism 70 comprises a driven member 71, a power output 72, two holders 73 and a rotating shaft 75.In preferred embodiment of the present invention, this driven member 71 is a conical gear, and this power output 72 is a roller gear.Each holder 73 is roughly a rectangular slab, and the center offers an axis hole 731.This rotating shaft 75 is passed the through hole 351 on the installation portion 35 rotationally and is placed in the axis hole 731.

This switching mechanism 50 comprises one first gear 51 and one second gear 53.This first gear 51 is used for matching with the internal gear 61 of first power take-off mechanism 60.This second gear 53 is used to drive described two driven members 71.

Please combine to consult Fig. 4, when assembling this switchover apparatus 100, at first, an end of this motor 40 is fixed on the base plate 11 of fixture 10.Extension 33 with housing 30 is sheathed on the keeper 20 again, and keeper 20 is installed on the fixture 10, and an end of baffle plate 13 is installed in the storage tank 21.Then, first power take-off mechanism 60 is fixed on the inwall of housing 30.Subsequently, first gear 51 and second gear 53 are fixed on the main shaft 41 of motor 40 successively.At last, 2 second power take-off mechanisms 70 are installed on the installation portion 35 of housing 30.The through hole 351 of installation portion 35 is passed in each rotating shaft 75, rotating shaft 75 is rotatably installed on the installation portion 35, again driven member 71 and power output 72 are fixed in the rotating shaft 75 through two holders 73.So far, accomplished the assembling of this switchover apparatus 100.

Please combine to consult Fig. 5 to Fig. 7, after these switchover apparatus 100 assemblings were accomplished, this housing 30 turned and axially is slidably mounted in the baffle plate 13 of fixture 10, and the auxiliary section 39 on this housing 30 is relative with the retainer 17 on the fixture 10.When housing 30 endwisely slips until the connecting portion 31 of this keeper 20 backstop housings 30 away from motor 40, this keeper 20 can prevent that housing 30 and fixture 10 are separated.The magnet 37 that electromagnet 15 repels on the housing 30 on this fixture 10, this first gear 51 can be meshed with the internal gear 61 of first power take-off mechanism 60 and export the torque along main shaft 41 directions, and are in first duty.Magnet 37, the second gears 53 on the electromagnet 15 attraction housings 30 on this fixture 10 can be meshed with the driven member 71 of said 2 second power take-off mechanisms 70 and export the torque perpendicular to main shaft 41 directions, and are in second duty.

When needs switch to second duty with first duty, at first,, make the electromagnet 15 on the fixture 10 be converted into the state of attracting each other by mutual repulsion with magnet 37 on the housing 30 with the both positive and negative polarity reversal connection of electromagnet 15.Along axially-movable, in the motion process of this housing 30, first power take-off mechanism 60 and first gear 51 that are installed on the housing 30 are separated this housing 30 under the effect of magnetic force.This housing 30 continues motion; Be meshed until second driven pulley of second gear 53 with 2 second power take-off mechanisms 70; Thereby is motion radially through said second power take-off mechanism 70 with the axial conversion of motion of motor 40, externally exports through power output 72.Auxiliary section 39 on this housing 30 and the frictional force between the retainer 17 on the fixture 10 make housing 30 and fixture 10 be in relative static conditions.

When needs switch to first duty with second duty,, make the electromagnet 15 on the fixture 10 be converted into relative attraction state from mutual repulsion with magnet 37 on the housing 30 with the both positive and negative polarity reversal connection of electromagnet 15.In the axial direction near fixture 10, the driven member 71 of this second gear 53 and second power take-off mechanism 70 is separated this housing 30 under the effect of magnetic force.This housing 30 continues motion, and first power take-off mechanism 60 that is installed on the housing 30 is meshed with first gear 51, rotates thereby this motor 40 drives this housing 30.

Be appreciated that switching mechanism 50 of the present invention can be a worm screw, accordingly, the internal gear 61 of this first power take-off mechanism 60 and the driven member of second power take-off mechanism 70 71 are the worm gear that cooperates with worm screw.

The switchover apparatus 100 of preferred embodiment of the present invention; With switching mechanism 50 relative fixed on main shaft 41; Through mobile shell 30, switching mechanism 50 selectivity are matched with first power take-off mechanism 60 or second power take-off mechanism 70 and realize the moment of torsion output of different directions, reduced the quantity of motor 40; Volume is little, has reduced the cost that uses and safeguard.

In addition, those skilled in the art also can make various modifications, interpolation and the replacement on other form and the details in claim of the present invention scope of disclosure and spirit.Certainly, these all should be included within the present invention's scope required for protection according to the variations such as various modifications, interpolation and replacement that the present invention's spirit is made.
